Rebirth of Conan as a Detective

Chapter 1183 “mathematics”

Chapter 1183 “Mathematics”

“Acheng,” the **** of the garden corridor found Gao Chengdao, “I heard the students here say that six months ago, a student named Shen Ting hanged himself and was concealed by the teachers.”

“half year ago?”

Gao Cheng thought of the motive of this case.

“Yes,” Yuanzi said with fear, “I heard that since then, the school has had Fukamachi’s curse, and there is still a cursed oil painting in the art classroom. The woman’s hair in the painting grows longer every day! ”

“What is the cause of suicide?”

“It seems that they are often bullied. It is the two people who died this time…”

Art room,

Gao Cheng followed Yuanzi to find the cursed oil painting.

A gentle woman hugs her baby. The painting is called “Lullaby”.

“I have previous photos,” Yuanzi opened the phone album and said, “It used to have short hair with ears, but now it’s longer.”

Gao Cheng made the comparison carefully, and then touched the paint of the painting.

In the painting, the woman’s hair grows longer… He is no stranger to this phenomenon. In order to hide the real painting, he repainted the surface with paint that can easily fall off. There have been such cases in the history of art.

He had even encountered it in a Nagano case before.

It’s not a curse at all…

“The author of this painting is that Fukamachi who committed suicide?” Gao Cheng asked unexpectedly after seeing the autograph.

“That’s right.”

A girl with long hair appeared behind them with a strange look. Yuanzi was almost scared to pee, and she screamed and hugged Gao Cheng hard.

“This painting contains the soul of Fukamachi classmates,” the girl smiled nervously. “The two guys were killed by the souls of Fukamachi, haha!”

Gao Cheng watched the girl leave madly and shook his head: “It feels like the people in this cram school are weird. How come you come to a place like this in the garden?”

Yuanzi: “If I failed the math exam, I just…”

Gao Cheng: “Just ask Xiao Ai to help you make up lessons.”

“Little Ai is more terrifying.”

…

“Police Department!”

Kogoro Mouri ran back to the scene of the crime from the faculty office hurriedly, waving an answer sheet excitedly and shouting.

“I know what’s going on! Teacher Ono has an alibi?”

“What?” Mumu, who was going to return to the police station, looked at the uncle in confusion, “What did I find? I don’t have time to circle with you, brother Maori! Really, every time…”

“It’s true this time!”

The uncle hurriedly handed over the answer sheet to Mugure.

“There were three exams here yesterday, two in the morning and one in the afternoon. Rento was killed just after the second, but you see, this is the answer sheet for Muroi’s third exam.

In other words, Muroi was killed after the third exam, but at that time Mr. Ono had been taken to the police station, right? ”

“Is this true?” Mumu checked in astonishment. “Indeed, Mr. Ono has an alibi… but she has already pleaded guilty at the police station just now. What’s the matter?”

“Anyway, the police department?” The uncle said anxiously, “Ms. Ono must be trying to shield the prisoner, that is, a certain student in this school!”

“Okay,” Mumu said cautiously, “it looks like we need to re-investigate, then you are the one to solve the mystery of the secret room, brother Maori!”

In the afternoon, the police found a ball of inflatable dolls in a bush outside the window of the secret room.

Uncle Maori felt that he had solved the puzzle and called everyone into a classroom.

When Gao Chenghe Yuanzi came over, they happened to meet the female teacher who was brought back from the police station.

It’s really beautiful…

Coupled with the aura of the teacher who loves the students, according to the logic of the uncle, it is completely impossible to be the kind of gentle type of the murderer.

The most terrifying thing is not this, but the always confused Maori uncle, who actually found a favorable clue this time, it was still in the absence of Conan.

More than extraordinary performance…

“Everyone,” Kogoro Mouri said with a light cough, “I think you all know the specific case. Now I want to say that Mr. Ono can’t be the murderer at all. The evidence is the answer sheet in my hand.

This is proof that Muroi took the third exam. At that time, Mr. Ono was taken to the police station, so it was impossible to kill Muroi, and of course it was impossible to kill Rento, because the two were obviously killed by the same person… ”

“But how do you explain the secret room, brother Maori?” Mumu asked.

“In fact, we were wrong at the beginning,” the uncle said to himself, “The body that Mr. Ono saw was not a corpse at first, but a disguised inflatable doll. The window in that room was small, and it was normal to misread it under low light ,

The evidence is the inflatable doll found outside the window, which should have been thrown out of the small window by the prisoner in a ball. ”

Mumu: “What’s the matter with the corpse? How can the prisoner come out?”

Maori snorted and laughed: “It’s very simple, because the corpse is the prisoner himself! This is a suicide case planned to frame Mr. Ono!”

“Self, suicide?!”

There was an exclamation in the classroom.

“Is this planned by Rento themselves?!”

“Yes,” the uncle nodded, “I’m afraid it’s because of too much pressure. I wanted to take revenge on Teacher Ono when I committed suicide!”

wrong……

Gao Cheng’s brows tightened.

The uncle’s reasoning sounds like there is nothing wrong with it, but it’s not right at all.

If the two students wanted to commit suicide, there was no need to have anything to do with “Fukamachi’s Curse”.

No matter how you look at it, it’s murder…

But what is the answer sheet?

Did Muroi really take the third exam?

Or was Muroi really murdered after Rento?

There were 3 exams. After the first 2 exams, the rest time was as long as 30 minutes. Rento was probably killed at that time. Then when the third exam started, a lullaby sounded and the body was found.

So, what is the time of Muroi’s death?

If Ono-sensei is the murderer, Muroi must be killed before Rendo…

“I see.” Gao Cheng raised his head suddenly, and ran into the faculty office in the wind regardless of the surprise of everyone around him.

The murderer will set the lullaby to be played at noon the next day, of course, to prevent the police from accurately determining the time of death.

If you want to have an alibi, you must make the police feel that Muroi was killed after the third exam, so they did a series of tricks.

Including deliberately leaving blood on the scene.

People subconsciously think that the murderer committed the crime in alphabetical order.

As for the evidence of the answer sheet…

“Sure enough,” Gao Cheng flipped through all the answer sheets for the 3 exams and confirmed his guess. “Counting the one in the hands of the uncle, there are only 2 Muroi’s answer sheets. If it weren’t for Muroi, he did not take the first exam , It means that the murderer replaced the answer sheet…”

“What do you mean?” The garden who helped organize the answer sheet was puzzled. “Muroi did fill in the answer sheet for the third exam, and didn’t the police also say it? It’s Muroi’s handwriting…”

“What if Muroi’s answer sheets are not in the third exam?” Gao Cheng interrupted, “The answer sheets for several exams are exactly the same except for the initial serial number, so it’s possible that Muroi filled in ahead of time…”

The serial numbers of the answer sheets for the three exams are 15, 16, 17, but Muroi only has 16 and 17.

Obviously someone did something…

Gao Cheng asked: “Who was the invigilator for the first two exams?”

Yuanzi: “Of course it is Mr. Ono. My test papers were issued by Mr. Ono himself.

“That’s right.”

All the clues were grouped together in Gao Cheng’s mind, and he had already solved all the female teacher’s methods.

“There is only one problem, motivation.”

In the art room, Gao Cheng took Yuanzi to the front of the cursed painting “Lullaby” again.

“Ah, Acheng?” Yuanzi felt that the art room was a little oozing, and retreated, “Or go back, maybe you will be cursed…”

“I want to confirm one thing.”

Gao Cheng took an art knife and began to scrape the hair from the oil painting.

Gradually, the watercolor paint on the surface of the painting fell off, revealing an earring in the woman’s ear.

Same as the one worn by the female teacher…

This should be the motivation.

The relationship between the female teacher and Fukamachi probably surpassed the teacher-student relationship.

…

It was the same classroom as before, but this time the one who gathered the crowd became Gao Cheng.

“Hello, what the **** are you doing?” a male tuition school teacher complained, “We are also very busy!”

“Hasn’t it been found out that it was a suicide? What the **** is going on, officer?”

“Don’t worry,” Gao Cheng said on the stage holding a stack of test papers, “Next, I just ask everyone to do a test for me.”

“Test?” Teacher Ono opened her mouth unexpectedly.

“Yes,” said the high-component questionnaire. “There are a total of 50 questions, with 5 options for each question. Please choose the one you think is the most correct. If you are unsure, you can choose any one.

The test time is 15 minutes from now, please start answering the questions. ”

“Really,” the male tuition teacher checked with the questionnaire, “What kind of ghost question is this?”

The questionnaire is full of questions related to this case. The first question is where to buy rope if you want to hang yourself.

After 15 minutes, the questionnaire was collected by the police and returned to Gao Cheng after the revision was completed.

“Hey, can you tell us now?” The male teacher asked, “What is the point of doing this kind of investigation?”

“This questionnaire can identify the real culprits who killed Nito and Muroi.”

Gao Cheng checked the scores.

“The above questions are basically clues to the crime investigated by the police. For example, the source of the rope in question 1. We found that it came from the convenience store interlocking, so the answer is the convenience store in the option.

The same is true for other questions. Except for the police, only the real murderer knows the correct answer to this questionnaire, but when the murderer knows this, he will definitely avoid the correct answer…

It’s just that I didn’t expect the murderer to avoid all of them.

All 50 questions were answered incorrectly, and the probability of getting a zero score is only four-fifths to the 50th power, which is one in 70,000, but some of you have got this score. ”

Gao Cheng’s eyes fell on the silent female teacher.

“Ms. Ono, the murderer who killed Nito and Muroi was the one who got all the wrong answers, right?”

“What are you kidding?” Uncle Maori responded strongly, “Doesn’t Mr. Ono have an alibi?”

“That was her alibi specially arranged,” Gao Cheng explained. “The reason why she found a detective to investigate the prank is to help herself find an alibi. This is only part of the plan.”

“How is it possible? The alibi can never be false, right?”

“Uncle, you can ask those candidates again. Indeed, for the 3 exams, lots will be drawn to change seats. It’s normal if you don’t see Muroi, but what if everyone doesn’t see Muroi? Is it normal?”

Gao Cheng took out Murai’s serial number 16 answer sheet and the serial number 15 standard answer sheet.

“This answer sheet of Muroi actually corresponds to the serial number 15, which is the answer sheet of the next exam 16 when the prisoner gave Muroi the answer sheet.

In the same way, in the second test, the prisoner sent Muroi the answer sheet with serial number 17.

I looked through all the answer sheets of the 3 exams and came to the conclusion that Muroi only took 2 exams and was killed before the 3rd exam or before Rento. ”

Kogoro Mouri’s face was stiff: “This… how could this be?”

“Do you know now?” Gao Cheng continued, “Ms. Ono’s alibi does not exist at all. Whether it is the previous killing chicken prank, the blood on the scene, and the exam answer sheet, it is only to mislead the killing order and give himself Just make an alibi.”

“Mr. Ono…” The uncle was deeply shocked and looked at the female teacher in disbelief, “Is it true? Are you just using me? I believe you so…”

Thinking about it carefully, the reason why he could think of looking for the test answer sheet seems to be indirectly guided by the female teacher.

The uncle was a few years old in an instant.

“But what’s the motive?” Mumu hurriedly asked, “What is Ono-sensei’s motive?”

“The motive should be this painting Gao Cheng brought the “Lullaby” from the art studio to the stage.

“Actually, this painting is based on the original painting and repainted a painting with paint that can easily fall off. After scraping a part, you can see that the ear part is actually wearing an earring.

Teacher Ono, it’s exactly the same as the one on your ear. ”

Upon hearing this, the female teacher raised her head and stared at the oil painting closely, her eyes gradually moistened.

“Fukamachi…”

…

A few days later, Gao Cheng came to the cram school again to pick up the garden.

This time the case allowed him to draw a “Mathematics” card, but unfortunately he couldn’t give it to Yuanzi for use. In the end, he only raised his “Mathematics” to the proficiency level.

It is better than nothing, but it corresponds to the university level, which can make his later study a lot easier.

“Mr. Ono has already pleaded guilty,” Yuanzi said in a low mood. “The third person she is going to kill is the long-haired boy who said Kaodong University. It seems that Fukamachi was hanged by those three people six months ago…”

Gao Cheng paused, thinking of the long-haired man in the corridor mocking him and Yuanzi.

Are all the guys in Kaodong University like this?

Or is it the problem of this cram school?

Originally, students often commit suicide, which is a big problem…

What do the parents think about sending their children to this kind of school?

Gao Cheng was puzzled and shook his head. Seeing the gloomy look of the garden, he grabbed the garden and said, “Beijing has opened a new western restaurant. It seems to be called Ai. Let’s try it together.”

Yuanzi: “That Aini Western restaurant, I heard that it is very popular, and I still have to book it.”

“Ai what restaurant?”

“Aini… asshole, don’t think I don’t understand Chinese!”
